  Flickering Weld Effect

  Posted by Ploughman on April 20, 2006 at 7:06 pm

  Im working on a logo that gets cut out by a plasma torch… ive got the emitter from PI and the rusty steel BG in AE7…
  i want to add a lense flare that flickers… I was wondering if there was an expression out there that could help me achieve this effect.

  Put The lens flare on a black layer animate the flare point then look in the Effect menu>animation presets>behaviors>opacity flash random.

  Maybe add a wiggle expression to the brightness of the lens flare. Something like:

  wiggle(6, 40);

  And I would highly recommend Knoll Light Factory, over the standard AE/Knoll 35MM lens flare. It even has some sort of welder torch preset, I believe.
